Magnetized materials
The Bohr–Van Leeuwen theorem, discovered in the 1910s, showed that classical physics theories are unable to account for any form of material magnetism, including ferromagnetism; the explanation rather depends on the quantum mechanical description of atoms. Each of an atom's electrons has a magnetic moment according to its spin state, as described by quantum mechanics. The Pauli exclusion principle, also a consequence of quantum mechanics, restricts the occupan… WebIn summary, it can be said with a fair degree of certainty that the Chinese were the first to notice the magnetic and "south-pointing" properties of magnetized materials. Although they first used these properties for geomancy, they also put them to use for direction-finding, which became the most significant use of such materials nearly 2,000 ...

WebEven though ferromagnetism is also found in nickel and cobalt, if you find a random piece of metal that sticks to a magnet, the metal is probably an iron alloy (steel). It’s really rare to see nickel- or cobalt-based alloys in everyday life, since steel is cheaper and stronger for most applications.
